Methods: Data from a longitudinal cluster randomized study involving 542 WESW (18-55 years), recruited from 19 HIV hotspots were analyzed. WESW were eligible if they were 18 years and above, exchanged sex for money or other goods and services in the last thirty days and reported one episode of unprotected sex. Data were collected at baseline, 6, 12, 18 and 24 month. The likelihood of mobility was measured by change in residence by WESW between baseline, 6 months and 12 months follow up. Participants who changed residence were considered mobile and those who never non-mobile. Generalized estimating equations were constructed to predict the correlates of likelihood of mobility among WESW.
Results: Preliminary analyses indicate that young age (b=-0.022, 95% CI=-0.036, -0.01, p=0.02), large household size (b=0.142, 95% CI= 0.069, 0.21, p<0.000), less children in the household (b=-0.19, 95% CI= -0.29, -0.10, p<0.000), alcohol use (b=0.12, 95% CI= 0.08, 0.16, p<0.000) and drug use (b=0.16, 95% CI= 0.12, 0.22, p<0.000) were associated with high likelihood of mobility among WESW. Married or in a relationship (b=-0.09, 95% CI= -0.17, -0.02, p=0.012), locality: rural community (b=-0.43, 95% CI= -0.71, -0.15, p=0.002), small towns (b=-0.52, 95% CI= -0.24, -0.8, p<0.000) and lower scores of post-traumatic stress disorder (PTSD) (b=-0.03, 95% CI= -0.04, -0.016, p<0.000) were associated with lower likelihood of mobility among WESW.
Conclusions: Preliminary results show that individual factors, behavioral factors and mental health-related challenges are associated with a high likelihood of mobility among WESW in Uganda. These results point to the need to address these factors in order to facilitate continued access to HIV related health care services among WESW, especially those in low resource settings.
